SPRIT FOR JIBS.

' SPECIFICATION forming part of Letters Patent No. 522,524, dated July3, 1894.

Application filed February 15, 1894. Serial No. 500,299. (No model.)

- State of Massachusetts, have invented certain new and usefulImprovements in Sprit Attachmentsfor J 1bs and I do hereby declare thefollowlng to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon,'which form a part of thisspecification.

The object of this invention is to provide the ib of a sailing vesselwith a sprit or spar whlch is movably connected to the j ib-stay at oneend and at the other to the clew of the ib to prevent undue bellying of,the sail and also prevent such accidents as are liable to occur fromthe jib fouling the jib-stay or other parts of the rigging. And theinvention consists in providing the spar with rollers which move uponthe jib-stay so that the spar will form a permanent attachment for thejib 5 and the invention further consists in the combination with thejib-stay of a spar having at one end separable rollers which are adaptedto engage the j ib-stay and prevent the detachment of the spar, theother end of the spar being attached to the clew of the jib, as will behereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View showing a part of the jib-stay and the sprit orspar with the fixture which carries the rollers. Fig. 2 is a detail viewof the attachment or .fixture for the end of the sprit or spar, showingthe same open, and Fig. 3 is a view showing the application of myinvention. V

A designates the j ib-stay and B the sprit or spar. The spar is providedat one end with a ferrule and opening for the reception of the shank cof the fixture O, the fixture being preferably made in two parts whichare pivoted to each other by a pintle c. The part adjoining the shank ismade integral there w1t h and presents side members c between which isjournaled a grooved roller 0 the ends of said members being reduced andapertured for the attachment of the other part of the fixture thereto.The part 0 of the fixture also carries a grooved roller and the ends ofthe side pieces of the same are recessed to receive the reduced ends ofthe part 0' and are provided with corresponding apertures for theconnecting pins. The object of this fixture is to provide rollers whichwill bear on each side of the jib-stay and which may be readily openedand when applied to the jib-stay will be securely held thereon. Therollers are preferably grooved so that they will prevent the sidemembers of the fixture engaging the jibstay and chafing thereon.

The 'end of the spar B opposite the fixture O is attached to the clew ofthe jib, and the length of. the spar is such that it will hold the sailflat. V

, This device does away with the employment of a spar at the foot of thejib, and is adapted to be applied on the jib-stay at a suitable distanceabove the tack of the jib.

The device hereinbefore described will hold the jib flat and preventexcessive bellying, so that in running before the wind the full area ofthe sail will be effective and there will be no liability of the sailfouling with the jib-stay. It will also be noted that a jib with thisattachment may be readily raised and lowered and that the jib may bereefed with the spar in place; also that the spar having a limitedmovement on the jib-stay will accommodate itself to the position of thejib.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. An attachment for the jibs of vesselscomprising a spar which is connected at one end to the clew of the jiband at the other endin movable engagement with the jib-stay,substantially as shown and for the purpose set forth.

.2. In combination with a jib-stay, a spar or sprit having rollers whichare adapted to engage with said jib-stay, the other'en'd of the sparbeing attached to the clew of the jib, substantially as shown and forthe purpose set forth.

3. In combination with a sprit or spar B, a

fixture made in two parts each carrying a with grooved rollers which areadapted to roller, said fixture being attached to one end embrace andmove freely upon the jib-stay, of the spar or spritand adapted to engagethe other end of the spar being attached to with a jib-stay, the otherend of the spar bethe ciew of the jib, for the purpose set forth.
